Containerized Storage Microservice with Direct Connection to Requesting Application Container

1. A method for processing IO requests from an application container using a containerized storage microservice, the application container and the containerized storage microservice executing in a containerized computing environment that implements a host operating system having a file system, the method comprising: intercepting an IO request within the application container; and bypassing the file system of the host operating system by directly connecting the IO request to the containerized storage microservice within the containerized computing environment.

2. The method according to claim 1 , wherein the IO request is directly connected to the containerized storage microservice through a file system module of a storage microservices stack that includes the containerized storage microservice.

3. The method according to claim 2 , wherein the application container is configured to include a library that intercepts the IO request and connects to the file system module of the storage microservices stack.

4. The method according to claim 1 , wherein directly connecting the IO request to the containerized storage microservice is through an encrypted connection within the containerized computing environment.

5. The method according to claim 4 , wherein the containerized storage microservice performs an authenticated access corresponding to the IO request by maintaining an application identifier and cryptographic hash corresponding to the application container.

6. A non-transitory computer readable medium storing program code for processing IO requests from an application container using a containerized storage microservice, the application container and the containerized storage microservice executing in a containerized computing environment that implements a host operating system having a file system, the program code being executable by a processor to perform operations comprising: intercepting an IO request within the application container; and bypassing the file system of the host operating system by directly connecting the IO request to the containerized storage microservice within the containerized computing environment.

7. The non-transitory computer readable medium according to claim 6 , wherein the IO request is directly connected to the containerized storage microservice through a file system module of a storage microservices stack that includes the containerized storage microservice.

8. The non-transitory computer readable medium according to claim 7 , wherein the application container is configured to include a library that intercepts the IO request and connects to the file system module of the storage microservices stack.

9. The non-transitory computer readable medium according to claim 6 , wherein directly connecting the IO request to the containerized storage microservice is through an encrypted connection within the containerized computing environment.

10. The non-transitory computer readable medium according to claim 9 , wherein the containerized storage microservice performs an authenticated access corresponding to the IO request by maintaining an application identifier and cryptographic hash corresponding to the application container.
